Do I need to boil lids and rings when canning?
Boiling lids and rings is a crucial step in the canning process to ensure the lids are properly sterilized and sealed. However, the method of boiling has changed over time. In the past, it was recommended to boil the lids and rings in water for 10-15 minutes to sterilize them. But with the introduction of new lid designs and materials, the process has been simplified.
According to the latest guidelines from the USDA, it is no longer necessary to boil the lids and rings. Instead, you can simply wash them in hot soapy water and rinse thoroughly. Then, place the lids in a pot of simmering water (180°F – 190°F) for 5-10 minutes to activate the sealing compound. This method is not only easier but also helps to prevent the lids from becoming overheated, which can affect their sealing ability.
What is the purpose of boiling lids and rings in canning?
Boiling lids and rings serves several purposes in the canning process. Firstly, it helps to sterilize the lids and rings, killing any bacteria or other microorganisms that may be present.
